Hi daniel, can i trouble you for your opinion??

How much horsepower/kilowatts do you want? suitable up to 230rwkw

What are you using the car for? street / drag / track. Reliability is a big issue (i use my line to drive all over sth est qld for work)

When do you want boost roughly? eg. 2200/2500 would be ideal but not run out of flow before 6000 minimum

Do you want power early or late in the rev range? - bit of both if thats possible.

What Mods you engine has or is going to have including computers or exhaust etc.?

3.5in turboback exhaust, r34gtt cooler, power fc (to come), walbro pump (to come)

Obviously, what car? 94 series 1 r33, manual.

Intercooled? and is it large, small, medium? see above (r34 cooler)

Still running AFM or upgraded or no longer there? stock / z32 one at later stage

Custom exhaust manifold or standard? standard - willing to go adaptor or custom manifold depending on whats cheaper/ easier

External wastegate or internal(limited to virtually 450hp)? internal

Could you give me some recommendations?

Also, what would be the approx cost all up?? (braided lines, external manifold/adapter if necessary and rough cost of a workshop to do labor).

ideally my budget would be less than 2500 installed.

Hope you can help with some info :P

It is very hard to retain such an early boost and still achieve high results. It sounds as though you are aiming for a highflow. I'm not too sure that th 34 cooler will do you any favours at 230rwkw but it should be ok. The higflows typically come on boost around 2800 and hold past 7000....you can expect to see full boost around the 3500 mark. The R33 highflow is reliable to approx 380-400hp so it will be the best package to do what you want it for. You won't need to change any of the lines or hoses...it will all just bolt straight back on in place.

Highflow is still $1800 depending on condition. Meaning it could go down to $1750 or up to $1850...but usually they stay at $1800. I charge $200 to remove and refit the turbo as long as you are in Brisbane somewhere.

There are other options with adapting a turbo to fit but the costs are usually not represented in the overall result compared to a highflow. For $2100 I can graft the exhaust housing of your turbo to the back of a GT30R which will still net you fairly early boost figures, you get the twin ball bearing cartridge as well. This would cost another $150-$200 in braid lines and roughly another $200 in intake modifications. Not the right setup for you though.

Hope I haven't confused you at all....just PM me if you have any other questions. or email at codered@bigpond.net.au

no wasn't looking to get 230rwkw just wanted the turbo to support around that much as a minimum. Once i wound the boost above say 15psi i would definatley change coolers,

anyway pm sent :P (actually pm sending..)

My RB20 Hiflow was capable of that horsepower figure.

At 17 PSI I put out 218 RWKW.

That 300 hp is roughly what they are rated to when hiflowed. It doesn't mean they are not capable of 450hp it just means they usually only last 12 months like that.

With your other question, the same turbo I am putting on mine would be a bolt on. It's a ball bearing turbo and rated at 450hp. usually 50hp higher can still be achieved SAFELY though. Plus being a BB turbo it will spool hell quick and will outlast a highflow RB25 turbo anyday, and for roughly the same price maybe a couple hundred more.

which turbo are you putting on?

Umm, that was a while ago now.

I ended up going for the GT2876R but altered the stock manifold to suit it, relocated the AFM and re-did some of the intake plus braided lines....all in all wasn't too much of a drama. The hardest part was adapting the T3 dump to the T25 housing.

This thing f**kING HAULS :sorcerer:

How much are they going for and how much do you think it would cost to get a mech to do what you did(Im in vic so couldnt get you to do it)

    • Hi All, New member here, I've joined to help my son with an issue that is truly doing our heads in. I'll start with a bit of an overview. Chris carried out some modifications to the engine to try and extract just a little extra power out of the motor and make it a bit more efficient. Previous to this work, the car already had an upgraded exhaust, increased boost up to 14psi, modified standard turbo to metal impellers and slightly oversized, upgraded fuel pump, been dyno-tuned at JEM, and some other bits n bobs like coil packs etc. Before the current mods it was making 236rwkw at 14psi but after the new mods it now makes 209rwkw at 14psi. The work he carried out is as follows, timing belt service, water pump replacement, return to sump radium catch can, had oem head rebuilt and machined 0.2mm, fitted Athena cut ring head gasket 1.2mm thick, arp 2000 head studs, added rear prp head drain, added an external wastegate 40mm turbosmart welded off the stock manifold and plumbed back into a 3in dump. The car has been on the dyno and apparently the ignition is working, fuel flow and fuel pressure is fine, injectors are fine, spark plugs are working fine, Maf is working, O2 sensor is working, TPs sensor is working, VCT is working, CAS is working, boost leak test showed no boost leaks, compression test first crank cold 135psi and got to 150psi across all cylinders once cranking, timing is confirmed at tdc with a dial gauge and the cam dots line up, no blockages in intercoolerm throttle body or pre-turbo intake, no blockages in exhaust, cat conveter or down pipe, turbo looks fine and spins and wastegate looks fine and is new. Soz for all the detail but after all this, it has been in 3 times for dyno and each time comes back stating it's not going to make power. After the first (or second, can't remember now) trip to dyno we did find the timing out by one tooth and this improved things, but it is still well down. Does anyone have any ideas?  Any replies much appreciated as we're just not sure of which direction to take this. Regards Rob (Chris's Dad).
    • That's just a gauge, with a certain amount of electronic damping, and no-one cares if it is timely-accurate. I'd hesitate to use it for an ECU MAP input without knowing that it was a nice signal. Responsive but smooth. Not laggy. Not lumpy.
    • Took the dirty BMW to an actual drag meet so I could do a legit full pass on a sticky enough track and had a quiet goal to try and beat my PB in the old R33 GTS25t The time to beat:  R33 on stock RB25, Internal gate GT3076R on stock manifold tuned to about 17psi on BP98 and running on drag tyres: F20 M135i with intake, dump pipe and MHD OTS Stage 1 tune on street tyres - didn't even drop the tyre pressure: Kinda similar, and kinda way different
    • Isn't there a fitting on the back of the balance tube? That's what the OEM boost gauge uses.
    • Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.
